示例1: DocumentLoaded
void DocumentLoaded(nsIDocument* aBindingDoc)
{
// We only need the document here to cause frame construction, so
// we need the current doc, not the owner doc.
nsIDocument* doc = mBoundElement->GetCurrentDoc();
if (!doc)
return;
// Destroy the frames for mBoundElement.
nsIContent* destroyedFramesFor = nullptr;
nsIPresShell* shell = doc->GetShell();
if (shell) {
shell->DestroyFramesFor(mBoundElement, &destroyedFramesFor);
}
MOZ_ASSERT(!mBoundElement->GetPrimaryFrame());
// Get the binding.
bool ready = false;
nsXBLService::GetInstance()->BindingReady(mBoundElement, mBindingURI, &ready);
if (!ready)
return;
// If |mBoundElement| is (in addition to having binding |mBinding|)
// also a descendant of another element with binding |mBinding|,
// then we might have just constructed it due to the
// notification of its parent. (We can know about both if the
// binding loads were triggered from the DOM rather than frame
// construction.) So we have to check both whether the element
// has a primary frame and whether it's in the frame manager maps
// before sending a ContentInserted notification, or bad things
// will happen.
MOZ_ASSERT(shell == doc->GetShell());
if (shell) {
nsIFrame* childFrame = mBoundElement->GetPrimaryFrame();
if (!childFrame) {
// Check to see if it's in the undisplayed content map...
nsFrameManager* fm = shell->FrameManager();
nsStyleContext* sc = fm->GetUndisplayedContent(mBoundElement);
if (!sc) {
// or in the display:contents map.
sc = fm->GetDisplayContentsStyleFor(mBoundElement);
}
if (!sc) {
shell->CreateFramesFor(destroyedFramesFor);
